CARTRIDGE-yE-JECTOR FOR FIREARMS.

SPECIFICATION forming part of Letters Patent No. 619,565, dated February14, 1899.

Application filed December 7, 1898. Serial No. 698,5 '75. (No model.)

To all whom it may concern.-

Be it known that I, ALVAH E. GRIMES, a citizen of the United States,residing at Norwich, in the county of New London and State ofConnecticut, have invented certain new and useful Improvements inEjectors for Firearms, of which the following is a full, clear, andexact description.

This invention relates to the shell-ejecting mechanism of breakdownfirearms, and has for its immediate object the provision of mechanismwhich may be controlled and actuated by the breaking down of the armeither to eject the shell forcibly and clear of the arm or may serve tosimply start the shell sufficiently to allow it .to be grasped andwithdrawn by hand. Mechanism capable of operating in a double capacity,as just described, is particularly valuable, in that the first-namedmethod of forcible ejection may be employed when paper shells are used,such shells being rarely reloaded and are therefore of no use after thefirst firing, or if reloadable metal shells be used the second method ofextraction may be employed and the retention of the shell easilyaccomplished. The latter manner of extracting the shells is particularlydesirable when using the arm where long grass, marsh,or underbrushabounds, as it avoids the loss of many shells which could not be foundwere they forcibly ejected in the first-named manner and saves much timethat would otherwise be spent in searching for and gathering in saidshells.

To assist in explaining my invention, I have provided the accompanyingsheets of drawings, which serve to illustrate the same, as follows:

Figure 1 shows, partly in elevation and partly in central verticalsection, an arm fitted up with my newly-invented improvements Fig. 6 isa cross-sectional view taken on the line 1 1 in Fig. 1. Fig. 7illustrates, partly in plan and partly in section, thepeculiarlyconstructed hinge-pin of the arm. Fig. 8 illustrates in planthe relative positions of certain elements of my newly-inventedmechanism.

. Referring to the drawings, the letter a denotes the frame of the arm;I), the barrel; 0, the barrel lug, and d the hinge pin or pintle, bymeans of which the frame and barrel are secured together and on whichthe latter is adapted to rock. I

The letteredenotes the hammer of the arm, 6' the trigger, and f a leverlocated on the top of the frame and adapted to move the bolt f, thatserves to lock the barrel against movement on the hinge-pin; butinasmuch as the operation and general arrangement of the severalelements thus far mentioned are common and well understood no detaileddescription or illustration is deemed necessary.

Referring now to the shell-ejector mechanism, the letter g denotes theejector-stem, located in a chamber 1) in the breech end of thebarrel-lug, beneath and parallel with the bore of the barrel. The rod 9is adapted to travel reciprocally in the chamber 1) and bears upon itsouter end a head g, which when the rod is in its inner position forms aportion of the s end of the barrel, said head g being cut out orcounterbored to receive the head h of the shell h. Confined in thechamber 19, between the inner end thereof and the confronting end of therod 9, is a spring 10, which seeks con-- stantly to force said rodoutward; but the movement of the latter in either direction is limitedby a screw 70, located, as shown, in the lug c, with its upper endentering a slot 9 provided in the rod g. When the arm is closed, the rodg is forced to its inner position (compressing spring Zc)by therecoil-block a, the head 9 of said rod being received in the end of thebarrel 1), which latter is cut away, as at 6 for that purpose. When thearm is broken down, however, as shown in Fig. 2, the spring is (ifallowed to act) expands and forces outward the rod g, the movement ofthe latter being of course limited by the screw it. It will be obviousthat when the head g, engaging thefiange h of the shell It, will forcesaid head from its position in the barrel.

' In connection with the ejector-rod g and the mechanism immediatelyrelated thereto I have provided mechanism that serves to lock the rod 9and retain it in its inner position until just before the operation ofbreaking down the arm is completed, when said locking mechanism isreleased, thus allowing the spring 70 to shoot the rod g rearward withforce sufficient to eject the shell clear of the arm. On the other hand,the said ejector-locking mechanism may be thrown out to allow the spring70 to force the ejector rearward slowly, resulting in simply startingthe shell from its home position in the barrel instead of shooting itclear of said barrel, as first explained. WVhen thus arranged, topartially extract the shell the rear end of the extractor-head g abutsthe recoil-head a and is allowed to gradually move rearward as thebarrel is swung upward from the frame, resulting in drawing the shellslowly rearward to a position where it can be grasped and completelyremoved from said barrel. The said mechanism for locking the rod 9 inits closed position embodies as one of its elements apeculiarly-constructed hinge-pin cl.

Pivotally supported in a recess 0', cut in the side of the barrel-lug c,is a lever m, whose pivotal support is a screw 72. The shorter arm ofsaid lever lies adjacent to the hingepin d, and the longer arm bears aright-angular extension m. To receive the said extension m, a recess 0is provided, leading from that end of the recess 0 adjacent the end ofthe barrel 1) at right angles to and across the chamber 1). A smallspiral spring 0 is located in a'hole in the longer arm of the lever m,the opposite ends of which spring abut, respectively, the bottom of saidhole and the lower wall of the recess 0, said spring serving to rock thelonger end of the lever m upward.

When the extractor mechanism is to act to eject a shell forcibly fromthe arm, as above explained, and the barrel is in its closed position,as shown in Fig. 1, the lever m is held in its normal (upward) positionby the spring 0 and the extension m enters a notch g in the rod g. Theend of the shorter arm of said lever then lies in a groove 01 in thehingepin d. When the arm is broken down, the end of the said shorter armof the lever m engages the side wall of the groove 01, thereby rockingthe longer end of the lever m and its extension m downward. Such rockingof the lever on continues as the barrel swings upon the hinge-pin duntil just before the arm is completely broken down the extension m iswithdrawn from the notch 9 thus allowing the spring to expand and shootthe rod 9 outward, the latter carrying with it the shell engaged by itshead 9 with suflicient force to throw the shell clear of the arm. Afterthe release of the bolt g,whioh occurs at about the time the shorter armof lever m travels from the groove d to the circumference of thehinge-pin, continued rocking of the barrel causes the said shorter armto simply ride upon said circumferential face of the pin d.

In the operation of reloading the arm a cartridge is inserted in thebarrel until checked by the rearwardly-projecting ejector-head. Thebarrel is then swung to its closed position in the frame, the cartridgeand ejector being meanwhile forced forward in the barrel by therecoil-head. Just as rod g reaches its inner position its notch g comescoincident with the lever extension m,which extension at once enterssaid notch and again locks the rod against rearward movement, theshorter arm of the lever having then entered the groove d in the pin 01.

Should it be desired to simply start the shell from its seat instead ofejecting it as just described, the hinge-pin d should be rotatedsufficiently to rock the end of the lever m, ongaging said pin, out ofthe groove cl before the barrel is broken down, as shown in Fig. 3 ofthe drawings. Such action rocks the longer end of the lever downward andwith draws its extension m from the notch g of the rod g, thus leavingthe rod free to ride gradually outward and upward on the face of therecoil-block a as the arm is broken down and correspondingly withdrawingthe shell, as above explained. Upon closing the arm rod g and thecartridge are forced forward by the recoil-block and are then retainedin such closed position by the engagement of the ejector-head g with theface of the recoil-block.

One end of the pin dis adapted to be screwed into the frame a and isscrew-threaded, as at d In order to readily rotate the pind to entirelyremove it from the frame, also to lock the same from rotation when inthe proper positions to produce either a forcible or partial ejectmentof the shell, the opposite end of the pin d is slotted,as at 01 toreceive the end of a radial arm or lever s, that is pivotally se curedin said slot by a pin 25. The pivoted end of the lever s is providedwith two notches 8, adapted to be engaged by a spring-pressed bolt 15,whose end engaging said notches is beveled, as shown, to permit therocking of the lever s to bring either of its notches 8 into engagementwith the said bolt 25. The notches s are so located in the pivoted endof the lever that the bolt i may serve to hold the lever 8 either inclose contact with the face of frame a or in an outwardly-rockedposition, as shown in dotted lines in the drawings. When said lever isrocked into close engagement with frame a, it (the lever) is received inone of two grooves a to prevent the rotation of the pin d when in eitherof its operative positions. Should it be desired to change from onestyle of ejectment to the other, it will be readily understood fromFigs. 4 and 7 that such change may be readily attained by simply rockingthe lever outward from the side of the frame a, after which the pin maybe rotated as desired and the lever s then folded into the proper groovea My newly-invented improvements are of Very simple construction, arereadily assembled, easily operated, and improve greatly the generalefficiency of the arm without adding greatly to its cost.

Having thus described my invention, I claim- 1. In a breakdown arm, incombination, a frame, a barrel, a grooved hinge-pin connect ing saidbarrel and frame, a notched springpressed ejector-rod mounted in thebarrellng, and a lever having one of its ends normally in engagementwith the ejector -rod
